Stilling basins with sudden expansions are one of the energy dissipation structures. In hydraulic jump, pressure fluctuations cause significant damages in stilling by cavity formation, erosion, and vibration. Roughness can also lead to changes behavior stream lines vortices. Despite large number works on topic, role roughness spatial jumps is not yet fully understood. Present research aimed stu...

We study the spin1 2 Heisenberg models on an anisotropic two-dimensional lattice which interpolates between the square lattice at one end, a set of decoupled spin chains on the other end, and the triangular-lattice Heisenberg model in between. By series expansions around two different dimer ground states and around various commensurate and incommensurate magnetically ordered states, we establis...

An Ornstein-Zernike approximation for the two-body correlation function embodying thermodynamic consistency is applied to a system of classical Heisenberg spins on a three-dimensional lattice. The consistency condition determined in a previous work is supplemented by introducing a simplified expression for the meansquare fluctuations of the spin on each lattice site. The thermodynamics and the ...

The extinction of a single species due to demographic stochasticity is analyzed. The discrete nature of the individual agents and the Poissonian noise related to the birth-death processes result in local extinction of a metastable population, as the system hits the absorbing state. The Fokker-Planck formulation of that problem fails to capture the statistics of large deviations from the metasta...

The hadron resonance gas (HRG) model is often believed to correctly describe the confined phase of QCD. This assumption basis many phenomenological works on QCD thermodynamics and analysis yields in relativistic heavy ion collisions. We use first principle lattice simulations calculate corrections ideal HRG model. Namely, we determine subleading fugacity expansion coefficients grand canonical f...

Sago starch is a locally grown and produced starch resource in Malaysia. In this study, corn starch to sago starch ratios (CS:SS) of 0:20, 5:15, 10:10, 15:5 and 20:0 were included in feed mixture to contain 20% starch and produce five isonitrogenous and isocaloric (30% crude protein and 16.7 kJ/g, respectively) tilapia Oreochromis sp < em>. diets. Diets were preconditioned to contain 40% moistu...
